<p>The present invention realize an automatic analyzer capable for controlling the gap between the tip of the sample nozzle and the bottom surface of the reaction container without relationship of the individual difference of a reaction container or a sample nozzle, and capable for restricting the sample attached to the tip of the sample nozzle. The movement distance of the arm 42 is calculated and stored the memory while the tip of the sample nozzle 11a of the sample dispensing mechanism contacts to the coordinate measurement stand until the stop position detector 44 detects the stop position detection plate 43. The sample nozzle 11a is moved toward the bottom surface of the reaction container 2, being stopped at the time when he stop position detector 44 detects the stop position detection plate 43, the arm 42 being moved upwardly for the movement distance stored the memory from this position. The sample nozzle 11a can be stopped in condition that the tip of the sample nozzle 11a is contacted to the bottom surface of the reaction container 2 and the bend (warp) of the sample nozzle 11a is restricted.</p> |
